SIGN -WRITERS PEN.

Application filed February 3, 1920. Serial No.

To all whom it may concern.

Be it known that I, FRANK X. KnarrEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful I mprovements in Sign-Writers Pens, of whlch the following is a specification.

The pen which is the subject matter of the present application for patent is designed more particularly for use by sign wrlters, and its object is to provide a pen which 15 so constructed that signs, show cards and the like can be easily written.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in'order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing, Figure 1 is a perspect ve view of the pen; Fig. 2 is a rear elevation thereof, and Fig. 3 is an enlarged crosssection of the pen blades.

Referring specifically to the drawing, the pen is composed of two flat blades 5 and 6, respectively which are fastened together at one end by a strip 7 bent over the edges thereof and riveted, as shown at 8: The other ends of the two blades are left free and form the writing portion of the pen,

the ink or other writing fluid which is held between the blades flowing from this end. Adjacent to the united ends of the blades, the latter are bowed outwardly, as shown at 9, these bowed portions being connected by a screw 10 on the projecting end of which is threaded a nut 11, whereby the blades.

may be spread more or less in an obvious manner according to the width of the letters or other characters to be formed.

The pen hereinbefore described is provided with a handle or holder 12 which is hollow to seat a soft rubber sack 13 con taining a supply of writing fluid. The handle is secured to the outer face of the blade 5 and has a side aperture through which extends a button 14 on the sack 13, said; button when pressed inwardly to compress the sack and then released, causing the writing fluid to enter the sack, the action being similar to an ordinary self filling fountain pen.

The handle 12 is secured to theblade 5 over an aperture 15 therein, said aperture opening into the space between the blades Specification of Letters Patent.

inner face of the blade 6, whereby the writing fluid is prevented from traveling upward and away from the writing ends of the blades, and the latter fill evenly for perfect control of the writing fluid.

The handle 12 extends at an oblique angle with respect to the pen blades 5 and 6, both rearwardly and laterally, and it will be noted that the handle is connected to the blades near the writing ends thereof. This makes it easy to keep the writing ends of the blades flat on the card or other surface, and also permits a blades without straining the latter, thereby enabling the operator to makecurves and strokes with a free-arm movement, and eliminating kinks and turns. The pen blades being set vertically when writing, makes it possible to move the same freely in any direction desired, in the same manner as a lead pencil, thereby making it very easy to form letters or other characters. The blades can be spread more or less by the screw 10 to obtain a heavier or lighter flow of writing fluid. The angle at which the pen is held also makes the lines, both vertical and horizontal, of the same width.

Back of the aperture 15, the blade 6 has a transverse rib 17 formed by an indentation. The rib is on the inner face of the blade 6 and is in contact with the inner face of the blade 5, and it acts as a fulcrum to permit the spacing of the writing ends of the blades by gathering or spreading the blades by means of the screw 10.

I claim:

1. A pen comprising a pair of flat blades connected at one end and free at the other, the latter being the writing end of the blades, and a handle connected to the rear side of the pen and extending at an oblique angle rearwardly and also laterally of the pen.

2. A pen comprising a pair of flat blades connected at one end and free at the other, the latter being the writing end of the blades, one of said blades having an aperture, a hollow handle secured to the last mentioned blade over the aperture, a reserheavy pressure on the voir for a Writing fluid in the handle and having its outlet positioned to discharge through the aperture into'the space between the blades, and a tongue extending from the apertured blade over to the other'blade, said tongue being located back of the aperture.

8. A pen comprising apair of fiat blades connected at one end and free at the'other, the latter being the Writing end of the blades, a screw connecting the blades for varying the space thereof, a transverse rib on the'inner facee'f one of the blades and engaging the inner face of the other blade, said rib being located between the Writing ends of the blades and the aforesaid screw, and a handle extending from the last mentioned blade.

In testimony whereof I affix my signature.

FRANK X. KEMPEL.
